I have written two new tutorials for DMedia
( http://dmedia.dprogramming.com/ )

- Getting started with OpenGL - creating a window
- Drawing basic primitives using OpenGL

Grab them while they're hot ;)

Nice! I just started reading, and noticed you're using toStringz for strings.
I've tried using SDL with D before, and I noticed that you don't need to use toStringz at all, for example, this works just fine:

SDL_WM_SetCaption("My SDL Window", null);

at least it worked when I tried it.

Please, please, please read the whole thing before you write comments like this one :S
Quote from my article:

`But then if you know the D specification inside-out, you might say “Hey, but when the compiler allocates space for string literals, it inserts an additional zero just after that memory range !”. Calm down, please, you can remove the toStringz function call and its associated import if you know what you're doing. But if someone wanted to have a window with some dynamically - generated caption, they would be in some serious trouble.`

That works because string literals in D are implicitly null-terminated, although the literal length won't reflect that.  The problem arises when you try to pass in a dynamically created string, which is usually not null-terminated.

Damn crossposted topic.  I hate these.

Per one suggestion from some time ago, I postedo to D.announce and D.learn so people can see the announcement and reply to D.learn... Not many do this though, I'll have to include explicit instructions ;)

Tom,
Well done on this site, the tutorials are a little basic but are good for anyone wanting to get started with SDL & OpenGL.

I had to do a Geometry refresh for tutorial 3 :) .

How about in the future a simple but effective 2D or 3D killer Game for D written in D, SDL &| OpenGL?

Keep up the excellent work

That's what I intended... I didn't want to send people over to NeHe, especially because I didn't like some of their explanations, like "we're going to discuss it in later tutorials" - expanations never came ;)
My tutorials are still lacking some images and descriptions but I hope I'll get there ;)

That's pretty inevitable when doing 3d graphics ;)

Hmmm... If you have any cool ideas, visit #dmedia on the irc.freenode.net server. I'm just going to sleep (my timezone is GMT+1) but I'll be there tomorrow ;) Maybe making a Pong or something like it would work...

as for a simple (but not simple enough for a tutorial) game:

Thanks ! :)

Looking good so far ;)

Sadly this seems to be the case, I hate Geometry but like 3D how much does that suck? ;)

Pong could be could, in 3D would be quite interesting no?

I played this it was simple but effective and could be a great way to do a quiz type thing at the end of a tutorial, the game made me laugh and the comments and assertions in the code made me laugh more, like the sense of humour :) it definitely helps when coding for sure.
